VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent No. 464,076, dated December1, 1891.

Application filed October 15, 1890. serial No. 368,177. (No model.)

To all whom it may concern:

Be it known that we, JOHN A.'LANNERT and WILLIAM R. J EAVONS, citizensof the United States, residing at Cleveland, in the county of Ouyahogaand State of Ohio, have invented certain new and useful Improvements inVapor-Burners; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

Our invention has reference to vapor-burn ers; and it consists in theuse of deflectors, in connection with perforated or open-workburner-tubes in which combustion occurs, and in other features ofconstruction and combinations of parts, all substantially as shown anddescribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central sectionalelevation of a burner provided with our improvements.

' oil-inlet arm a'forpipe connection.

Fig. 2 is a separate perspective view of the combined air and flamedeflector cone and head set loosely upon the top of the inner tube. Fig.3 is a view of a modification.

On the burner itself as an article of manufacture we make no claim, theinvention therein contained being subject-matter of Patent No. 438,548,dated October 14, 1890.

A represents the burner bowl or base having a Vapor-distributing chambera, and an Vaporization of the fluid occurs when the burner is heated, asin regular use, in or about the inlet a, and the continuous chamber athus becomes, essentially, a vapor distributer, in which thevapor underits own pressure travels or is carried around to all parts of the saidchamber and escapes therefrom under equal pressure at all points throughthe narrow neck or channel a into the free space between theburner-tubes. The burner here shown is circular; but the shape or formis side of the vapor-outlet from the chamber a,

through the narrow neck or passage a These tubes are filled withnumerous fine perforations a, through which air is admitted to to feedtheflame; but hydrocarbon vapors are liable to considerable and quickexpansion under the'influence of flame, andthus it occurs at the pointwhere combustion beglns and where in this case there is not suflicientair to make combustion complete that more or less vapor is liable to beforced out through the perforations c unconsumed and to escape into theair, causing disagreeable odors in the room and robbing the burner tothat-extent of its fuel. Thisliability is especially noticeable when theburner is first started and when it has been turned lowan effect 110-ticeable in common oil-lamps. We overcome this objection and defect bymeans of deflectors, which extend around about the sides of theburner-tubes, as shown, and serve to convey the escaping vapor or gasback into the burner-chamber to be consumed. Thus we have three severaldeflectors E, F, and G, lo cated as seen in Fig. 1. The inner deflectorE is secured to the inner tube B, and the outer deflectors F and G aresecured to the outer tube 0, and the said deflectors are so arrangedthat they will concentrate and carry back into the burner-chamberbetween the tubes any vapors or gases that may escape from theburner-chamberthrough the perforations c at any point below the point ofattachment of said deflector or 'perchance from about the burner.

Sometimes in starting the burner more or less oil may creep out upon itsouter surface and vaporize there as the burner becomes heated, and thisvapor would be diverted by the deflector into the flame and be consumed.Both of these deflectors extend down near to or about or below theburner-bowl, and terminate above at such elevation that though theburner be turned low the gases which may have escaped will be carriedback into the burner-space and into the flame and be con-' sumed ratherthan enter the perforations above the low flame, and thus get awaywithout being burned, as they might if the detact with the tube orchimney and inverselymore air on the flame below its point of conbyslightly retarding the air immediately above 1t, causes the tube tobecome intensely heated at a lower point than would occur if thedeflector were not used. The tube being n close metallic connection withthe diffusing or generating chamber causes it to heat more quickly andto a more intense degree, thus contributing to the efficiency of thedevice for vaporizing heavy oils. The deflector G is fixed to the outertube at or near its top, and extends down to the plane of the burner, ornearly thereto, and serves to intercept any escaplng vapor not caught bythe plate F, or that may escape above the same. We have shown three suchdeflectors attached by rivets or otherwise at different elevations; butthe number thereof and the position may be varied.

II is a combined air and flame deflector, as well as ashield for theburner. This part consists of the head h and the conical tube It. Thehead and tube can be separated, but are preferably made in a singlepiece, and the head s provided with vertical ribs 7L at intervals nside,and has parallel slots 7L3 formed about its side. In form it has theshape of asection ot acone, its narrower portion resting on the top ofthe inner burner-tube and its wider portion extending outward asufficient distance to protect the combustion-chamber between the tubes.For this purpose, as well as to divert the air laterally through slots bthe topof the head is closed, as seen in Fig. 2, and the bottom is open.The conical-shaped deflectortube h extends into the space within theinner tube a greater or less distancesay half way the length of thetube-andis open at its bottom, so that a free air-passage is formedthrough the same and through the lateral slots 77, in the head. Byclosing .the top of the flame-deflecting head hwater is prevented fromspilling into the burner-chamber between the tubes, and by giving thehead ventilation through the slots h or equivalent openings the head isfree of disagreeable odors, and at the same time fresh air is suppliedto the flame-diverting surface 72, of the head and thus contributing toperfect combustion of thevapors. The outer deflector G serves as ashield for the burner from the outside, as well as to form an avenue tolead the air and outside gases into the burner-chamber.

In Fig. 3 we show a modification in which the two lower deflectors standat right angles to the sides of the tubes, and the flame-deflectin ghead has a plain cylindrical extension instead of one that is conical.

The invention is understood to comprise deflectors connected with theburner-tubes, however constructed or arranged, provided they serve thepurposes herein set forth.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a burner, parallel perforated tubes forming aconibustion-chamberbetween them, and a perforated flame-deflector arranged at the top ofthe inner perforated tube to make a si'ibstantially continuousperforated wall with said inner tube, substantially as described.

2. In a burner, parallel perforated tubes forming acom bustion-chamberbetween them, the inner perforated tube rising to a greater height thanthe outer tube, and cover of greater diameter than the inner tube toprotect the chamber and closing the top of said inner tube,substantially as described.

3. In-a burner, the parallel perforated tubes forming acombustion-chamber between them, in combination with the deflector-headflaring outwardly and upwardly from the top of said inner tube andperforated on its flaring surface, whereby a substantially continuousinner perforated wall is formed through and by said head, substantiallyas described. I

4. A "combustion-chamber formed by two concentric perforated tubes, anda burnerbowl supporting said tubes and having an airpassage through itscenter into the inner of said tubes, in combination with anair-inflector in the lower portion of the inner tube and having acentral air-passage, substantially as described.

lVitness our hands to the foregoing specification this 7th day ofOctober, 1890.
